IMPROVEMENT IN PAVlORS RAMMERS.

Specification forming part of Letters Patent No. 162,384, dated Apiil 20, 1875; application filed March 29, 1875.

To all whom it may concern Be it known that I, GEORGE HIIOHCOOK, of Philadelphia, Pennsylvania, have invented certain Improvements in Paviors Rammers, of which the following is a specification:

The object of my invention is to provide a paviors rammer with a head or ram, which can be readily and securely attached to the wooden body, and this object I attain in the manner which I will now proceed to describe, reference being had to the accompanying drawing, in which- Figure l is a vertical sectional view of my improved paviors rammer; Fig. 2, a view of the parts detached from each other; and Fig. 3, a sectional View of an ordinary paviors rammer.

The ordinary method of constructing a paviors rammer is shown in Fig. 3, in which a ierrule, D, is first fitted to the lower end of the wooden body A of the rammer, and pieces 00 of wrought-iron then driven into the same, around the inner edge of the ferrule D, until the circle is complete, this ring of pieces on around the wooden center forming the mm B. As powerful blows are required to drive the pieces :0 into their places, and as each piece has to be driven separately, this plan is necessarily tedious and expensive. Moreover, the ferrule D has a tendency to slip down over the edges of the pieces after the rammer has been used for a time. I obviate these objections by constructing the head B of the rammer as shown in Figs. 1 and 2-that is, by casting it in one piece, preferably of steel, and forming on it a number of wedge-shaped projections, a, between which and the ferrule D the wood of the body A is compressed when the head is driven into its place. A central stem, 0, is also formed on the head B, and through an opening near the end of this stem is driven a key-pin, d, which also passes through the body of the rammer and serves to retain the head securely in its place.

I claim as my invention A paviors rammer having a solid metal head, B, on which are formed wedge-shaped projections a, and a central stem, 1), all being constructed for attachment to the wooden body A, substantially as and for the purpose herein set forth.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

GEORGE HITO HCOOK.
